    Disable EFI bootloader Windows 10

    I managed to solve the problem on askUbuntu forum. Basically, the Acer systems requires some additional steps inside BIOS (to mark "trust" the Ubuntu's EFI files and set them as 1st option as boot option), for enabling Ubuntu's Grub2 bootloader to start before Windows 10. Now everything works. I don't have to use EasyBCD inside Windows 10. Have a great weekend everyone!

    Disable EFI bootloader Windows 10

    Hello and thank you for your answer. I disabled the Hibernation as you said (now i don't have the 'Turn on fast startup (Recommended)' inside Power Options), but after a restart, nothing changes, still boots into Windows 10. From what i've read i think the EFI detects another bootloader at startup and deletes it (Linux's grub2), because normally, after Ubuntu's installation it should boot directly into grub2 bootloader (i attached a picture). I'm using EasyBCD usually to repair the Windows Metro bootloader (picture attached - it should look just like the screenshot) to chose from it which OS i want to use.

    Disable EFI bootloader Windows 10

    Hello guys, i have a problem regarding dual-booting Windows 10 along Ubuntu. After installing Windows 10 and Ubuntu after it, i'm no longer able to boot into Ubuntu, it starst directly into Windows 10. In Windows 8.1, i could chose at startup which OS to run (using Linux's grub2 or Windows Metro bootloader). I have Secured boot option disabled inside BIOS. Also if i want to use EasyBCD 2.3 to edit boot settings, i get a warning that EFI Bootloader is detected. Is there a way to do it? Thanks!
